Optimisation details of TWG 1.8.8

I currently do some courses at W3C about mobile web development with html 5 and I did a lot of improvements at TWG from the stuff I learned there.

Since TWG a optimized .htaccess is coming with the download which enables compression and caching of the web server. If you have an Apache web server I recommend to use this file by simply unzipping the htaccess.zip. Furthermore all css files a dynamically combined and compressed. the compress css files is stored in the cache folder for one day. You can disable this optimization during setup by setting $optimize_css = false; or you can delete this file by clearing the session cache (in the administration or by clicking on the bandwidth icon.

Below I have listed the measurements I have made with TWG 1.8.7 and TWG 1.8.8:

So now you see a lot of numbers. Lets write a small summary of the most important numbers:

Use the provided htaccess. Up to 55% less data is transfered compared to TWG 1.8.7. It even boosts the page speed score of TWG 1.8.7 to 90!

Up to 42% less requests are used in TWG 1.8.8. This is for the basic system. The more images you have the more requests of course you get.

The table does not show the optimized loading of resources. So the real time for loading the page should even be better.

Please note: The css files in the main directory are not used anymore. They have been moved to the css folder!
